XW PRO - THD Maximum input

Will a modified sine wave generator with 15-25% Total Harmonic Distortion properly drive a XW PRO inverter/charger or will it be rejected?

To close this, a gent I spoke to today said that you must not use a generator whose output is significantly distorted compared to the Pro inverter’s output voltage waveform because when the pass through relays close any differences between the gen waveform and the Pro waveform will cause nasty spikes/currents to flow between the two power sources.

So not only is using a generator, with a modified sine wave output with a grid-tie hybrid inverter, a bad idea, it’s apparently a very bad idea.

If there is something I am missing here that makes this conclusion incorrect, please jump in an explain.

Best regards,
